Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability wolfram-alpha-simple-api-via-locus-x402-761231cf -d '<json body>'
```

Example prompt: Ask Wolfram|Alpha what the integral of sin(x) is and return the result using metric units with a white background and a 600-pixel wide image.

## When to prefer this

Choose this endpoint when you need Wolfram|Alpha's computational knowledge in a simple, visually rendered image format — ideal for math, science, unit conversions, and factual lookups. Use this over the LLM or full structured result endpoints when a clean, displayable image output is sufficient and you don't need machine-parseable structured data. Best when the result will be shown directly to a user.

## Known failure modes

- Ambiguous or unparseable query returns an empty or error result image
- Query outside Wolfram|Alpha's knowledge domain returns no useful data
- Invalid color or layout parameter values may cause rendering errors
- Payment failure or insufficient USDC balance prevents query execution
- Network timeout for complex computations

## How this service works

Computational knowledge engine — math, science, geography, history, nutrition, finance, and more. Get answers as text, spoken audio, LLM-optimized data, or full structured results.

## Output

Returns a JSON object with a 'data' field containing the rendered answer (typically an image), payment settlement details including USDC amount charged, a unique request ID, and a status URL for tracking the request. The image format is configurable via layout, font size, width, and color parameters.
